AP PIARATUS FOR DELIVERING MEASURED QUANTITIES OF LIQUOR.

Patented Sept. 26, 1911.

Application filed September 12, 1910. Serial No. 581,572.

To all whom 'it may concern:

. Be it known that I 'DoUcLAs Giurrrrns,

' subject of the King of Great Britain, residing at No. 5 Josephineavenue, Brixton,

London England, have invented new and useful fm rovements in Apparatusfor Delivering easured Quantities of Liquor, of which the following is aspecification.

This invention relates to an improved contrivance for serving liquors inautoma ti- -callymeasured qauntities from an inverted bottle or other.vessel which is not open to the atmosphere at its upper end. The

contrivance is of that type in which a 5 measuring chamber is filled byopening a communication between the upper side thereof and the bottle orother vessel, the

contents of the measuring chamber being evacuated by opening acommunication from the lower end thereof to the atmosphere subsequent tothe closure of the passage by which the'chamber is filled. In. suchcontrivances the refilling of the. measuring chamber must be accompaniedby the displacement of the air. contained in the otherwise empty chamberto the bottle or other vessel simultaneously with the admission to 1'the chamber of a corresponding volume of liquor and, after thecompletion of the re filling operation, the liquor will follow theupward' flowing air and completely occupy the upward passage for the airup to the level of the liquor in the bottle or other vessel. Thereby anexiact hydraulic balance will be efl'ected within the downward passagefor the liquor and the upward passage for the air which, according tothe arrangements of previous inventions, prevents or delays therefilling of the measuring chamber 40 when, after evacuation of itscontents, it is again placed in communication with the bottle or othervessel. Now according to the present invention, the arrangement is suchthat the operation of the evacuation of 46 the contents of the measuringvessel has the eflfect of emptying of liquor a portion ofthe passagethrough which air rises .into the bottle or other vessel and substitutesair for the liquor in that portion so that, when the 60 measuringchamber is again placed in communication with the bottle or othervessel, the pressure in the downward flow passage for the li nor willpredominate and the refilling wi l commence promptly and take 3placer-rapidly. This constitutes the entirely new feature of the presentinvention the absence of which in prior inventions has caused them tofail in achieving the purpose desired.

The accompanying drawing shows an embodiment of the invention.

In this drawing Figure 1 is a part sectional front elevation showing themeasuring chamber open to the bottle. Fig. 2 is a corresponding sideelevation not in section. Fig. 3 is a sectional front elevation of aportion showing the measuring chamber closed relatively to the bottleand open to the atmosphere, and Fig. 4 is a corresponding sectional sideelevation taken along the line 44 of Fig. 5.

In this drawing the bottle a is secured in a liquid-tight manner to theserving contri- ,vance by the insertion of the spigot 1) into the mouthof the bottle when the latter is upwardly directed, the inversion of thebottle taking place by angular displacement around a hinge at c. In thespigot 12 and the base thereof, a passage 12* is formed for p the flowof liquid from the bottle to a measuring chamber (i there being a secondpassage I) also connecting the measuringchamher with the bottle, whichpassage may be continued upward within the interior of the bottle by atube b as shown, but this is not essential. The two passages 12 and bare commanded by the plug 6 of a turn-cock, the holes 6 and e in theplug which complete the passages b and b respectively,

' when the said holes are vertically directed,

being bored diametrally through the plug e. From the measurin chamber ata vertical. passage f is provlded leading downward to a spout g, theassage being commanded by the plug it of a second turn-cock formed witha diametrally bored hole It. The lever arms 6 and h*-securedrespectively to the said plugs e and h are interconnected by a link zand one of the plugs, the lower one as shown is provided with anoperatin lever h which,on being angularly displace downward, firstcloses the passages b and I) which connect. the measuring chamber withthe bottle and then opens the passage f which leads fromthe measuringchamber to the spout g, owing to the holes e, e and M being sufiicientlynarrow in the radial directions of the plugs e and h, for the holes 6 eto become covered by solid portions of the base of the spigot 12 whichconstitutes of the volume of air which is torced up the passage 6 by theliquid descending through 6 'will be followed by liquid which, if thereis a tube 6 will stand therein at a level which differs from that in thebottle only toan amount due to the superior capillary action caused bythe relatively small diameter of the'tube 6 If, after closing thepassages b b and emptying the chamber d, the passages 39 b were reopenedwithout any displacement of the liquid contained in either of them,there would be no initial tendency to refill the chamberwith liquidthrough )1) because the head therein would be balanced by that in thepassage 6 According to the present invention the pres sures in the twopassages are-thrown out of balance by the extraction of the liquid fromthe lower end of the passage 6 during the inflow of air from theatmosphere to the chamber 03 in the operation of emptying it of liquid.For this purpose a hole 6 is bored in the base of the spigot 12 whichconstitutes the shell of the plug 6 which hole leads from the atmosphereinto the beforementioned diametrally bored hole 6 of the plug a. Also ahole e is bored in the plug 6 as far as the hole 6 this hole 6 beingverticaliand in line with the lower end of the passage 6 when theoperating lever k is depressed to the position to discharge the contentsof the measuring chamber. The inflow of air through 6, e and the lowerend of the passage 79 to the upper end of the measuring chamber willempty this passageof liquid and substitute air, while the hole e will befullycharged and in the portion of 12 between the plug and the measuringchamber, the liquid will be retained by the fact that air will be unableto freely enter to take its place. To insure the retention of liquid inthe lower end of the passage b it is somewhat constricted at its ex--tremity as'shown. Accordingly when the plug e is again displaced intothe position to open the passages 17 b the head of liquid contained in bwill be sufiiciently less than that in the passage 6 to enable thechamber to promptly refill with liquid and displace the air upward fromthe measuring chamber through the passage 6 The evacuation of thecontents of the measuring chamber will commence. under a relativelyconsiderable head and therefore with a correspondingvelocity. Theinitial momentum of, the stream in the discharge spout thereby acquired,causes the stream to continue the evacuation with a velocity in excessof that due to the head which gradually diminishes to zero. Inconsequence of this rapidity of evacuation the last drop of liquid. inthe spout will be drawn through, and dripping avoided.

The linkz' carries a cam-piece a", which,

when the link is moved downward by the upward displacement of the leverk d'isplaces against the influence of a spring 7' the pivoted lever j ofa counter is and causes the claw of a pawl m pivoted to the lever y' topass over a tooth of a ratchet wheel a, mounted on the spindle of thecounter k. On the return movement of the link i,'the lever j will bereturned by its spring to its initial position, thereby drawing back thepawl m while the latter is in engagement with a tooth of theratchet-wheel n, whereby the counter will be actuated to registeranother unit. The upper and lower ends of the cam-piece z are beveled at2' which bevels,

by coming in contact with the lever arms 6 charge the'contents of themeasuring chamber and the reverse movement effected by the operation ofthe spring 0.

The bottle is secured in the upright position by a spring-catch p andlocked by a padlock g the bow of which is passed through a hole formedin a rod 1' the upper bent endof which fits in the recess formed in theinverted base of the bottle, the rod being inserted downward through atube 8 which carries clips 8 which embrace the sides of the bottle.

The contrivance may be secured to awallplate or fastened to a stand t asshown.

I claim:

In a contrivance for delivering liquid in automatically measuredquantities from a vessel, a measuring chamber, between said vessel andsaid chamber a double ported plug-cock one port of which has a lateralbranch and the shell of which is formed with two passages both extendingbetween saidwessel and the plug of said cock and with two passages bothextending between said plug and said chamber and with an air inlet incommunication with said lateral branch in the closed condition of-saidplugcock, a plug-cock. beneath said chamber and means so interconnectingsaid plug-cocks that one opens after the other closes.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
